IMPROVEMENT IN GRATEGLEAMNG ATTACHMENTS.

Specification forming part of Letters Patent No. 147,713, dated February17,1874; application filed January 29, 1874. i

To all whom it may concern Be it known that I, ADOLPH TIENSGI-I, ofMemphis, in the county of Shelby and State of Tennessee, have invented anew and Improved Grate-Gleaner Attachment; and I do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the accompanying drawing forming a part of thisspecification.

My invention is an improvement in the class of grate'cleanin gattachments formed of a rockshaft, provided with lateral arms, whichwork up and down between the grate-bars. The invention relates to thearrangement of footlevers with the grate for supporting and .operatingit, as hereinafter described.

I11 the accompanying drawing, Figure 1 is a front view, and Fig. 2 acrosssection, of a grate provided with my improved cleaning attachment.

A is a fire-place grate of the ordinary or suitable construction. Thecleaning attachment is formed of the curved bar 13 and blades or fingersG. The bar is pivoted to the under side (near the rear cross-bar) of thegrate, and the fingers project forward and curve upward to adapt them tobe worked up and down between the gratebars, when the bar is oscillatedor swung on its pivots. A foot-lever, D, is pivoted to the side bars ofthe grate, and connected with the bar B by means of a curved bar, E. Thelevers D project laterally from the grate, so as to be removed from theinfluence of greatest heat, and for convenience of access of operationby the foot. The fingers are maintained or supported in the horizontalposition by means of the'foot-lever connection, aswill be readilyunderstood from the draw ing. Thus the grate may be cleaned at any timeby merely placing the foot on one of the levers D, and depressing it tocause the fingers G to rise between the grate-bars; and, on removing thefoot they fall by their own weight and that of the superposed coal,cinders, and ashes.

I claim- The combination, with the grate and cleaning attachment B O, oflink E and the footlevers D, pivoted to the side bars of the grate andextended or projecting laterally, as shown and described, for thepurpose specified.
